Regular water changes also help IMO.

When I feed (a mix of all kinds of frozen foods of all sizes) I turn off all pumps and what the fish don't eat I see it settle on the corals and they consume it. I let the tank chill for at least a half an hour then I turn the display powerheads on and the fish begin to munch again on all the stuff that settled to the bottom and has been stirred up again. An hour later I turn the refugium/return pumps on.
